METHOD OF TREATING TEXTILE PRODUCT CONTAINING HIGHLY CROSSLINKED ACRYLIC POLYMER FIBER BEFORE DYEING, METHOD OF DYEING THE TEXTILE PRODUCT, TEXTILE PRODUCT TREATED BEFORE DYEING, AND TEXTILE PRODUCT

Document Type and Number:

WIPO Patent Application WO/2002/022942

Kind Code:

A1

Abstract:

A textile product, such as a yarn, woven fabric, or knit, which contains fibers of a highly crosslinked acrylic polymer (fibers obtained from acrylic fibers by partly hydrolyzing the nitrile groups to form amide groups and carboxy groups) is dyed without causing a difference in hue between the highly crosslinked acrylic polymer fibers and the fibers used in combination therewith. The method of treatment before dyeing comprises a pretreatment step in which the textile product, such as a yarn, woven fabric, or knit, which contains fibers of a highly crosslinked acrylic polymer is immersed in an acid liquid and treated at a high temperature under pressure. Also provided are: a method of dyeing which comprises, after the pretreatment, dyeing the textile product by a technique which is commonly used for dyeing the fibers used in combination with the highly crosslinked acrylic polymer fibers; a textile product obtained by the method of pretreatment before dyeing; and a textile product obtained by the method of dyeing.
